Hey... That's how I like to work. I draw a few thumbnails just to get the idea down, and if I get a series of forms I like, I embellish the rough idea into a sketch. Three point perspective can be tricky. I've used dynamic symmetry for years to help with that as it gives me a good basis for those low pass "Helicopter" shots. I have NO idea what they use these days though.

Yeah got to start somewhere thumbnails are handy for brainstorming.
I been trying to push my self with more dynamic perspectives once in a wile. I think it finally clicked for me but it took returning back to basics fundamentals for a bit for it to really sink in.
I haven't used much in the way of dynamic symmetry girds I keep composition in mind but I mostly been eyeballing compositions for what looks neat in the navigation window (cus if I can make it read from a distance on a tinny composition it should theoretically work larger scale)
Then I make a grid and make it proper after that. I find I get to tensed up in my drawing if I start with the gird.
Anyway sucks that the work was loss but You probably see this concept revisited latter on .

Daaaang I like this concept and definitely keep these around! The thumbnail process is a good one.

Thank you Sethtriggs. I'll probably revisit it latter on with a bit more fineness but The concept are still there from the early work.
